Bulgari Octo Finissimo Collection Review

Key Points from the Discussion

• The Bulgari Octo Finissimo Automatic's BVL 138 micro-rotor movement requires a high number of rotor revolutions—specifically 2170 clockwise rotations per day—to maintain its power reserve, significantly more than the 800-1200 revolutions typical of many other automatic movements.
• Micro-rotor movements, including those from Piaget and Patek Philippe (Caliber 240), are generally less efficient than full-sized rotors and may require specific arm movements or higher activity levels to stay fully wound, often leading to unexpected stops even after an active day.
• The BVL 138 movement in the Octo Finissimo is noted as one of the most demanding micro-rotors in terms of activity required for winding, surpassing even the winding needs of Piaget and Patek Philippe's 240 caliber.
• The original poster confirmed that using a watch winder overnight and then wearing the watch actively resolved initial concerns about the watch stopping, aligning with the explanation of the micro-rotor's winding requirements.
• Another owner reported no issues with the automatic winding of their Octo Finissimo despite extensive daily wear and water activities, suggesting that individual activity levels and wearing habits can significantly impact winding performance.
